Be it known that I, ALFRED C. SMITH, a citizen of the United States, and a resident of thecity of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved atch, of which the following is a full, clear, and exact description.

This invention relates to watches and has for an object to provide an improved construction wherein a simplified structure is presented including a combined ease and movement.

Another object. of the invention is to provide a solid pan or body for the casing and a movement mounted directly thereon.

A still further object is to provide a simplified and. cheap construction of watch which will be substantially dust proof and which will present a minimum number of parts.

In the accompanying drawing Figure 1 is a longitudinal vertical sec- 9' Elli tional view through a watch disclosr embodiment of the invention.

Figure 2 is a fragmentary sectional view through Figure 1, approximately on line 22.

Figure 3 is a view similar to Figure 2 but showing the parts inverted.

Figure at is a View similar to the righthand portion of the structure shown in Figure 3,*the same being on an enlarged scale.

Figure 5 is a perspective view of the casin shown in Figure 1, the same being inverted.

Figure 6 is a fragmentary vertical sectional view through the upper part of the watch shown in Figure 1, the same showing part of the setting mechanism.

Figure 7 is a pers )ective view of aspring embodying certain features of the invention.

Figure 8 is a perspective view of the winding stem.

Figure 9 is a perspective view of the double prongcd spring.

Referring to the accompanying drawing by numerals, 1 indicates the casing which is provided with a body or rim 2 and an integral top plate 3, which plate is provided with suitable apertures for receiving certain of the shafts or arbors of the movement. As shown, the ring or edge 2 of the casing is provided with grooves and 5 whereby small and substantially resilient flanges are presented for receiving a snap back (2 and a snap or bezel '1". If preferred, however, these members could be secured in some other way, as for instance, by being screwed into position. i'rrranged on the plate or top 3 is a. dial 9 of any usual or preferred structure above which the usual hands 10 are mounted though protected by the crystal or glass 11 carried by the bezel 7. The hands are connected to the respective shafts l2 and 13 in the usual manner, which slu. s are connected to the movement 14. It will be understood that the movement 1 is of any us to certain parts hereinafter specifically pointed out. It will, therefore, not be necessary to explain in detail the various connections said COHIIGCLlOHS are usual unless specially mentioned.

A number of setting gears are provided in the usual way as shown in Figure 6, gear 15 beingoperatively associated with the setting pinion l6 embodying certain features of the invention. This setting pin is normally loo. mounted on the winding shaft 17. and continually meshing with the gear 15. A winding pinion 18 is also carried by the shaft 17 and normally fits over the squared portion 19 thereof, said pinion having a squared aperture for receiving said squared portion. The pinion 16 is also provided with a squared aperture so that when the winding tar crown 20 is pulled outwardly and the shaft 1'? moved longitudinally, the squared portion will [it into the squared aperture 21 in the pinion 16 whereby the l or preferr d kind except in respect pinion and associated parts may be caused" to function for moving the hands sired. The shaft is rotatably 10 as de l. and slidably mounted in a suitable block which is secured in position in any desired 1 anner, as for instance, by the screws. The shaft 17 in addition to having the squared part 19, is provided with an enlarged knob 23 rounded on its periphery and a. stop 2-1 spaced from the knob 23.

lVhen the parts are in their normal posi tion as shown in Figure 4, the prong 25 of spring 26 is resting on the shaft 17 between the knob 23 and stop 26 whereby the Sllflftl is held so that the squared portion 19 will be positioned in the squared aperture or pinion 18. This will allow a. person to wind the spring whenever desired as hereinafter described.

hen it is desired to set the hands, the

crown 20 and shaft 17 are pulled outwardly until the stop 2-1- engages the prong 27 of spring 26, which prong will prevent the entire removal of the shaft 17. When the parts are moved to the position just described, the squared portion 19 will be fitting into the aperture 21 of pinion 16 and by a proper rotation of the shaft 17, the hands 10 may be adjusted as desired. When this has been done, the parts are again pushed back to the position shown in Figure 4. As the parts move back and forth, the prong 25 will slide over the knob 23.

In order that the spring, which is of usual construction, may be wound properly, the winding pinion l8 continually meshes with the idler pinion 28 which is held in position by a journal member 29 connected to the enlarged end 30 of the spring 31. The enlarged end 30 is pivotally mounted in position on the screw 32 whereby it may move to a limited extent as the spring 31 permits. The pinion 28 is formed with an elongated aperture through which the screw or ournal 29 passes whereby when the parts are turned in the reverse direction, the pinion may move away from the gear wheel 33 without functioning while it will rotate said gear wheel when operated in the correct direction. A pawl 34, commonly known as a click, is provided and acts in connection with the gear wheel 33 to prevent a reverse rotation thereof, said pawl being held to its work by the spring 31. The gear wheel 33 is provided with a squared aperture for accommodating the square shaft 35 which is connected with the usual spring of the watch, which spring is associated with and forms part of the movement 14. It will be noted that the various arbors and certain other parts of the movement are mounted on the plate 3 and also on the usual train bridge 36. It will be understood that the plate 3 is bored or formed with suitable apertures for receiving the various jewels or other members which are necessary to be supported in certain positions. It will also be noted that the movement is not a separate item from the casing but the casing and movement are made inter-dependent or built up as a single complete watch structure whereby certain parts of the watches heretofore known are eliminated.

What I claim is:

1. A watch including in its construction a winding and setting mechanism formed with a pair of pinions, one acting as a setting pinion and the other as a winding pinion, said pinions being formed with polygonalshaped openings in the center, and a winding shaft formed with a polygonal-shaped section adapted to be moved into the open ings in either of said pinions for causing an actuation thereof when the shaft is actuated.

2. A watch including in its construction a movement having a winding and setting structure, said winding and setting structure being formed with a winding and setting shaft provided with a squared section, and a pair of spaced stops, winding and setting pinions carried by said shaft formed with squared openings, a spring having a prong normally arranged between said stops, said shaft being movable longitudinally so as to bring said squared portion into either of the squared apertures of said pin- 1ons.

3. A watch including in its construc tion a movement formed with a Winding structure, said winding structure including a winding pinion, a shaft for operating said winding pinion, an idler pinion meshing with said winding pinion continually, a piw otally mounted support for said dler pinion, a winding gear wheel normally meshing with said idler pinion, a pawl for preventing said gear wheel from moving in one direction, and a spring for causing said pawl to function and to resiliently hold said idler pinion in mesh with said gear wheel.

4. A watch including a winding structure formed with a gear wheel, an idler pinion, a swinging plate for supporting said pinion, a spring for normally holding said plate in position so that the pinion will mesh with said gear wheel, and means for rotating said pinion, said swinging plate permitting the pinion to move away from the gear wheel when rotated in the wrong direction.
